BB Chevy Intake Gaskets RECT. PORT 1.82in x 2.54

The FEL-PRO BB Chevy Intake Gaskets RECT. PORT 1.82in x 2.54 is an OEM-quality replacement gasket set engineered for big block Chevrolet engines requiring precise port sealing at the intake manifold. These rectangular port gaskets are essential for builders and mechanics restoring or modifying classic big blocks, as a compromised intake gasket leads to vacuum leaks, coolant seepage, and erratic idle conditions that mask deeper tuning work. FEL-PRO's reputation for reliability makes this gasket set the trusted choice for serious engine work where air-tightness directly impacts carburetor tuning, EGR function, and overall drivability.

Constructed from composite material at 0.12 inches thick, this gasket kit is designed to withstand the thermal cycling and pressure fluctuations of big block operation while maintaining a reliable seal across repeated heat cycles. The 1.82 x 2.54 inch rectangular port dimensions are precisely matched to common big block Chevy intake manifold casting patterns, ensuring proper alignment without overhang or gap that would compromise seal integrity. The composite construction resists fuel permeation and coolant degradation better than traditional cork gaskets, extending service life and reducing the frequency of intake manifold disassembly for re-gasking.

This gasket set is ideal for big block Chevy platforms—including 396, 427, and 454 engines—whether you're performing a stock restoration, mild street build, or aggressive carburetor and ignition tuning. Installation requires standard intake manifold removal and careful surface preparation; lightly cleaning the casting surfaces and avoiding over-torquing manifold bolts ensures even gasket compression and prevents warping. Keep this kit on hand during any intake manifold work, as reusing old gaskets risks vacuum leaks that complicate carburetor synchronization and engine diagnostics long after the project is complete.
